Kitting out your bike with a shiny new groupset – the entire integrated gearing and braking system – is a great way to improve the slickness and overall performance of your machine. Whether you are building up a frame from scratch, or replacing your existing set-up, buying the kit as a groupset is better value than buying each part individually. In addition, replacing all the parts at the same time reduces the likelihood of premature wear in individual components. We stock Shimano and SRAM for mountain bikes, and also Campagnolo for road bikes.
